PurposeThe study assessed welfare of migrant and non-migrant labourers on cocoa farms in Ghana, using multidimensional poverty index (MPI) with four dimensions (education, health, dietary diversity, living standards) and 21 indicators. Specifically, we examined and compared non-monetary welfare of migrant and non-migrant labourers on cocoa farms in Ghana by adopting MPI approach. Also, we explored the factors affecting labourers' welfare.Design/methodology/approachA sample of 400 labourers was used. Qualitative and quantitative data were used. Quantile regression was used to investigate factors affecting labourers' deprivation in the different domains of non-monetary welfare.FindingsLabourers on cocoa farms are generally deprived in all the welfare indicators. Apart from having low education, labourers were underfed and lived under poor conditions. Though both migrants and non-migrants were multidimensionally poor, welfare of the later was higher than the former. Welfare of migrants and non-migrants on cocoa farms are influenced by similar factors: secondary occupation, income, credit accessibility, nature of contract and distance to social amenities.Research limitations/implicationsFor migrants, permanent status improves welfare. To improve labourers' welfare for enhanced productivity, cocoa farmers should provide permanent/long-term contracts for labourers and government should provide social amenities in cocoa-producing communities.Originality/valueMost previous welfare studies focused on farmers, with little attention paid to welfare of labourers on cocoa farms. We examined and compared the factors that affect migrant and non-migrant labourers' welfare on cocoa farms in Ghana. Moreover, we adopted the MPI (non-monetary) approach to assess labourers' welfare, instead of the expenditure and income approaches prevalent in literature.
